On Wednesday (October 1), "Decode" premiered on "Twilight" author Stephenie Meyer's official Web site, making it the first bit of new music to be heard from the soundtrack. The post on StephenieMeyer.com also says that the soundtrack's release has been pushed back to November 4, from the previously reported October 28 date. (The movie hits theaters on November 21.)

"The song is about the building tension, awkwardness, anger and confusion between Bella and Edward," Paramore frontwoman (and "Twilight" fan) Hayley Williams said in a statement. "Bella is the only mind Edward can't read, and I feel like that's a big part of the first book and one of the obstacles for them to overcome. It's one added tension that makes the story even better."

A source at Atlantic Records (which is releasing the album along with music supervisor Alexandra Patsavas' label Chop Shop) confirmed to MTV News that Paramore are scheduled to shoot a video for "Decode" sometime around October 13.

Late Tuesday night, Perry Farrell confirmed via press release that he too will have a new song on the soundtrack. "Go All the Way" will feature production work by Nine Inch Nails' Atticus Ross and Alan Moulder. More details on the soundtrack — including a complete track listing — are expected to be announced on Meyer's site over the coming days.
